Our story

SA dealers have always answered every call — until the day they couldn't.

In the European market, the global diago team had spent 3 years answering 250,000+ inbound calls a month across more than 60 automotive groups. Service desks that used to drop one-in-three calls were now answering every single one — at 2am, on Sundays, during European bank holidays. The mathematics held everywhere they shipped.

The mathematics also held when one of our South African founders watched their local dealership take six rings to pick up a Saturday-morning service booking. "We're booked. Can you call back Monday?" The Monday call never came. A R12,000 booking walked over to a competitor.

That same week we started spinning up diago Africa — the South African arm of diago, with local founders, a local board, local engineering. POPIA-compliant from day one. Bilingual from day one. Built for South Africa, from day one.

We launched publicly in May 2026, with three early-adopter dealer groups in Gauteng and the Western Cape. Within weeks, the missed-call list was gone at all of them.

What we believe

Four principles we'll defend in any meeting.

We work in voice. Voice is intimate, fast, and unforgiving. These are the rules we use to keep ourselves honest.

01.

Picks up first, talks second.

The first measurable promise of any voice AI is that the phone rings and someone is on the other end. Nothing else matters if you don't clear that bar.

02.

Local data, local people.

Customer voices belong on South African servers. Onboarding is run by South Africans who know what a "service plan" actually covers.

03.

Hands off the steering wheel.

diago doesn't try to be your CRM or your DMS. It feeds them. The systems your team already trusts stay the source of truth.

04.

If it's wrong, we say so.

Every call is transcribed and audited. When diago mis-hears or mis-routes, we surface it — and ship a fix.

How we got here

From a Parisian prototype to a South African floor.

2023

diago is founded in Paris.

Two Polytechnique-trained AI engineers (Sylvain Delgendre & Pierre de Boisredon) team up with Guillaume Couzy — former Managing Director of Stellantis France — to build the first version of diago, a French-language voice agent for a single Citroën dealership in Lyon. The pilot lasts four weeks before three more dealers ask to use it.

2024

diago expands across Europe.

Multilingual rollout: French, Spanish, Italian, Portuguese, Dutch. By December: 20+ dealer groups across 6 countries, ~40,000 monthly calls handled.

2025

60+ groups, 250k calls / month.

diago becomes the default voice agent for European automotive aftersales. Native DMS connectors land for Kerridge, CDK, Pinnacle, Autoline. Active expansion into Germany & the Netherlands.

Early 2026

South Africa pilot.

A quiet 8-week pilot with an early South African dealer group. POPIA architecture designed. Afrikaans added to the language stack. SA team begins recruiting across South Africa.

May 2026

diago Africa (Pty) Ltd launches.

Three early-adopter dealer groups go live in Gauteng & the Western Cape. Local team of 6 across engineering, customer success, and dealer onboarding. South African servers in production. diago.co.za launches publicly.
